In addition to the complete standard program of distribution transformers, Ruhstrat is specialized in the planning and production of individual customized cast-resin transformers. This includes amongst others converter transformers and fast-charge stations. The converter transformers cover power up to 10 MVA and series voltages up to 36 kV. Ruhstrat cast-resin transformers have a couple of features which distinguish them from others in technical terms and make them a very reliable and safe solution.
In order to ensure optimum products, we only use materials of first-class suppliers, such as grain-oriented electrical sheets, winding material made of aluminium and copper in band and peel technique, as well as high-quality insulating material (cast-resin, Mylar, Nomex).
For our customers this has the following advantages:
- High surge voltages are controlled reliably.
- Thermal reserves allow overload in a certain time range.
- Temperature shocks are overcome reliably without damage.
- High durability is guaranteed.
